Break a marble sculpture with Voronoi Fracture and Dynamics.

In this presentation from SIGGRAPH 2017, artist Eric Smit shows off the new features added to the Voronoi Fracture object in Cinema 4D R19. He walks through all of the major steps involved in creating an effects-quality shot of a marble bust breaking apart as it hits the ground.
He begins with a description of how he sculpted the head and how he then reduced it down to a reasonable polycount using the Polygon Reduction object and the Sculpt Baking system. He moves on to a general discussion of how to use the Voronoi Fracture object - creating good looking results with only a cube. He closes out by applying all the earlier techniques to his more complicated model including dynamics tools like Connectors.
